Abstract

A push bar assembly for an operating vehicle is provided. The push bar assembly includes a telescopic bar, a tow eye, a hitch assembly, and a spring assembly. The telescopic bar includes a first tube, a second tube and a spring-lock pin. The second tube is configured to move inside the first tube. The spring-lock pin is mounted on the first tube and configured to restrict the telescopic motion of the second tube inside the first tube. The hitch assembly includes a first end, a second end and an eye. The hitch assembly is configured to couple the telescopic bar with the operating vehicle. The tow eye is coupled to a second end of the second tube. Further, the spring assembly is mounted on the first tube and is coupled to the hitch assembly.

What is claimed is: 
     
         1 . A push bar assembly for an operating vehicle comprising:
 a telescopic bar comprising:
 a first tube with a first end and a second end; 
 a second tube with a first end and a second end and configured to telescopically move inside the first tube; and 
 a spring-lock pin mounted on the first tube, the spring-lock pin is configured to restrict a telescopic motion of the second tube inside the first tube; 
   a hitch assembly comprising
 a first end coupled to the operating vehicle; 
 a second end coupled to the telescopic bar; and 
 an eye; 
   wherein the hitch assembly is configured to pivot corresponding to the operating vehicle about a first axis and the telescopic bar is configured to pivot corresponding to the hitch assembly about a second axis wherein the first axis is substantially perpendicular to the second axis;   a spring assembly mounted on the first tube of the telescopic bar, the spring assembly comprising
 a housing; 
 an end cap of the housing; 
 a connecting rod having a first end and a second end, wherein the first end of the connecting rod is coupled to the eye of the hitch assembly; 
 a stopper coupled to the second end of the connecting rod; and 
 a spring wound around the connecting rod and disposed inside the housing between the stopper and the end cap; and 
   a tow eye coupled to the second end of the second tube.   
     
     
         2 . The operating vehicle of  claim 1 , wherein the operating vehicle is a rotary mixer.
